The purpose of this study was to investigate the effects intraradicular moisture conditions and canal morphologies on filling quality iRoot SP with single-cone technique in root canals. Eighty-four human single-rooted premolars canals were pair-matched similar volumes, aspect ratio (AR) curve shapes, 3D models after micro-computed tomography (micro-CT) scanning establish baseline consistency. Root then prepared assigned 4 experimental groups respect condition tested: (1) Paper point normal...
SBR process evolved from activated sludge process. Because the long cultivation period of and treatment effect can not meet needs production life, related variant improved came into being. Since 21st century, with development automatic control technology, has become a widely used technology. This paper introduces technology improvement process, puts forward suggestions for Technology in field sewage treatment.
This study aimed to identify a viable solution for the development of China’s electric power industry in line with “dual carbon” objectives. Accordingly, we collected and analyzed 2230 policy documents spanning 25 years track Chinese government’s focus on sector over time using latent Dirichlet allocation topic modeling. Our results reveal that area emphasis differs across different stages development. By analyzing evolution implementation, identified actions taken by government agencies at...
In order to investigate ecotoxicity effect of 2,4-dinitrotoluene (2,4-DNT) freshwater fish(Brocarded carp), the acute toxicity test and sub-lethal expriment were conducted in lab. The show that 96h LC50 value 2,4-DNT Brocarded carp is 19.67 mg/L. Its rating moderately toxic fish. Based on result test, fish was exposed different concentrations (1/2LC50, 1/4LC50, 1/16LC50, 1/256LC50, surface water standard concentration) killed at 3, 7, 10 14 day after exposure. activities Superoxide Dismutase...
The structure and surface chemical properties of activated carbon after nitric acid modification their influences on adsorption catalytic ozonation red 3R were investigated. results showed that both specific area micropore volume decreased, but mesopore increased modification. capacity performance modified influenced due to the acidic functional groups. was enhanced under condition dispersion interaction between groups 3R. increase in also considered be responsible for improvement alkaline...
Methanogens play an important role in the anaerobic digestion and production of methane, show significant influence on performance wastewater treatment process. Then methanogens granular sludge samples from full-scale UASB bioreactors treating avermectin or starch were detected by FISH using 16S rRNA gene-based probe functional probes. The results showed that hybridization simultaneous with mcrA probes was high coincident coincidence degree about 60%-80%, implying preferable consistency...
This study analyzes the microbial community and diversity composition of activated sludge in anoxic/oxic (A/O) treatment systems at different operation stages using Illumina MiSeq high-throughput sequencing to investigate structure for starch wastewater treatment. The experimental results showed that production A/O was quite stable under same condition, dominant bacteria were Proteobacteria, Bacteroidetes, Chloroflexi, Firmicutes, Actinobacteria. most important bacterial group Proteobacteria...
According to the problems exist in cyclic utilization of washing wastewater, coagulation tests utilizing ferric trichloride (FeCl3), alums, poly aluminium chloride (PAC) and polyacrylamide (PAM) are studied, respectively. Experimental results show that PAC was much better than other coagulants removal LAS chroma as a single coagulant. Cast 2.5mL PAC(10%) into quantitative rate reach 82.5% 87.8%, When mix every two kinds coagulants, maintaining same total amount coagulant 2.5mL, cast1.0mL...
The surface properties and performance of activated carbon (AC) used for catalytic ozonation were investigated after nitric acid modification (N-AC) Cu (II)-loaded (N-Cu-AC). results showed that the could increase amount functional groups AC. As a result, adsorption capacity activity AC be improved. N-Cu-AC synergistic effect on ozonation, where was more stable. an effective reusable catalyst ozonation. highest TOC removal efficiency 58.0% achieved when 60 min-catalytic treatment red 3R.
In order to study the effects of microbial nutrients on degradation living garbage and water quality leachate, Vitamin C,KCl,KH 2 PO 4 , NH Cl a mixture KCl,KH were added into anaerobic landfill garbage.The height settlement each litter layer concentration leachate COD ammonia nitrogen investigated.Experimental results show that C, KCl, KH can accelerate garbage, among which vitamin C had best effect accelerating degradation.
Using granular activated carbon (GAC) as electric particle electrode and heterogeneous catalyst loaded metal oxide to replace insulated in bipolar packing bed cell (BPBC), the electro-heterogeneous catalytic oxidation system was constructed. Adopting impregnation method prepare γ-Al 2 O 3 supported catalysts containing Cu Ce, it evenly mixed with GAC construct materials. stainless steel anode, porous graphite cathode materials between them, landfill leachate treated by an electro-catalytic...
